A clinical comparative study of an outpatient treatment group and an endoscopic sinus surgery group for maxillary sinus fungus ball.

Purpose: This study aimed to clarify the differences in the pathophysiology of maxillary sinus fungus balls (FB) among different case groups and to identify which patients with maxillary sinus FB would be suitable for outpatient procedures.

Methods: Thirty-four patients diagnosed with maxillary sinus FB between January 2017 and December 2021 were divided into two groups (O and S). We retrospectively compared the clinical and imaging characteristics, and the treatment outcomes between the groups.

Treatment strategies for orbital gas-producing necrotizing fasciitis secondary to odontogenic maxillary sinusitis: Technical notes.

This paper presents treatment strategies for orbital necrotizing fasciitis (NF) in a case of a 33-year-old male diagnosed with orbital NF, which developed after dental root canal treatment. Although orbital NF is rare, it is rapidly progressive and can easily lead to the loss of tissue and visual function, sometimes to a life-threatening extent. Prompt and adequate treatment has been a challenge yet remains quite essential.

Characteristics and utility of combined duplex color-coded ultrasonography in the cervical rotational position with head MRI and MRA in the differential diagnosis of apogeotropic direction-changing positional nystagmus.

Objective: To determine whether cervical ultrasonography, magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA) are useful in the differential diagnosis of etiology and understanding the pathophysiology in cases of apogeotropic direction-changing positional nystagmus (DCPN).

Methods: Thirty patients with apogeotropic DCPN were classified into 11 cases of central disease, seven cases of mixed central and peripheral disease, and 12 cases of peripheral disease by differential diagnosis based on various balance function, neuro-otological, and imaging tests.Cervical ultrasonography using the cervical rotation method and MRI and MRA of the head and neck were performed in most patients with apogeotropic DCPN.

A Report of Two Cases of Malignant Tumor of the Maxillary Sinus Diagnosed Using Fine-Needle Aspiration Cytology.

Primary and metastatic malignancies arising in the sinuses are rare and histologically diverse. The role of fine-needle aspiration cytology (FNAC) and the cytomorphologic characteristics of these tumors have not been specifically addressed. We described two cases of suspected malignant maxillary sinus tumors in 85- and 90-year-old patients with comorbid conditions, both of whom underwent tissue biopsies that failed to yield a definitive diagnosis.

Orbital Abscess Developed Apart From Paranasal Sinusitis and Dacryocystitis in Fibrous Dysplasia.

A 48-year-old man visited the emergency department of our hospital with swelling of the left upper and lower eyelids from the day before. On the first examination, he had severe swelling of the left upper and lower eyelids, proptosis, and chemosis. Left intraocular pressure was 33 mmHg.

Large Cholesterol Granuloma of the Middle Ear Eroding into the Middle Cranial Fossa.

Background: Cholesterol granuloma of the middle ear is extremely rare in comparison to cholesterol granuloma of the petrous apex but sometimes shows an aggressive course.

Case Report: We report herein a case involving a large, aggressive cholesterol granuloma of the middle ear that eroded the middle cranial fossa. A 64-year-old woman presented with pain in the left ear and hearing loss.

Lacrimal dacryostenosis with severe facial pain misdiagnosed as trigeminal neuralgia.

A 47-year-old woman developed intermittent shooting pain around the right side of the nose and eyes. A neurologist initially diagnosed trigeminal neuralgia, but carbamazepine did not improve the pain. Two months later, she presented with a pus-like eye discharge and was referred to us for further examination.

[Histological study on the effects of ethanol injection on mouth mucosa contraction loss].

We previously reported that a loss of contraction in the mucosal tissue of the palate arch is effectively induced by ethanol injections of moderate concentration and dosage. The present study was performed to obtain more information on how such ethanol injections induce contraction loss in mucosa tissue. Guinea pigs of both sexes were used in this study.

[Immunohistochemical study for monoamine neurons in the brain of unilateral inner ear impaired rats].

Patients with inner ear impairment have complaints of vertigo and also occasionally depression. The present study was undertaken in order to evaluate changes in monoamines which have reportedly been closely related to depression, using cisplatin-induced unilateral inner-ear impaired rats. A dose of 0.
